Operation Definition

Cutting out or off, without replacement, a portion of a body part

Procedure Overview

This family covers excision procedures performed on general anatomical regions rather than on a single named organ - areas such as the neck, chest wall, back, abdominal wall, buttock, perineum, and the retroperitoneal or mediastinal spaces. A surgeon cuts out a portion of tissue from one of these regions, leaving the rest of the body part in place and not replacing what was removed. Common reasons include removing a suspicious lump for biopsy, taking out a mass or growth that does not clearly belong to a single organ, or debriding a limited area of diseased tissue.

Because these regions sit between or around named organs, excisions here are often diagnostic - a piece of tissue goes to pathology to determine whether something is infection, scar, or cancer. They may also be therapeutic, such as removing a soft tissue tumor from the chest wall or a mass in the perineum.

Patients are told about this procedure when imaging or a physical exam finds an abnormal area that cannot be safely watched and needs to be sampled or removed.

Anatomy & Axis Detail

Upper Jaw

The upper jaw encompasses the maxilla and its associated alveolar ridge and hard palate, forming the bony platform for the upper teeth and the floor of the nasal cavity and maxillary sinuses. Excision of this structure removes a portion of bone or attached soft tissue, typically for odontogenic cysts, benign fibro-osseous lesions, or malignant tumors invading the maxillary bone, and surgeons must weigh the proximity of the orbital floor, infraorbital nerve, and sinus cavities when planning the extent of resection. Because the maxilla contributes to facial contour and oral function, documentation of an upper jaw excision typically specifies whether alveolar bone, palate, or sinus wall was involved, since reconstruction planning depends heavily on how much structural support remains afterward.

Approach: Percutaneous

Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.

Coding & Documentation

A code from this family is assigned when the operative note documents cutting out a portion of tissue from a general body region - not a whole organ, layer, or body part with its own dedicated body system table. The surgeon's language ('excised,' 'resected a portion of') and the specific region named in the note both drive code selection, since the qualifying body part values here are broad regional terms rather than organ names.

The most frequent assignment error is reaching for these general-region tables when a more specific body system actually applies - for example, coding a breast lesion excision here instead of under the breast-specific body system, or a skin lesion under the integumentary system instead. Coders should confirm the tissue excised truly falls into a general region (mediastinum, retroperitoneum, abdominal wall, and similar) before defaulting to this family, and should distinguish partial removal (excision) from removal of an entire body part (resection), which uses a different root operation.

Commonly Confused With

ExtirpationExtirpation of a general region is often confused with excision, but extirpation removes solid matter that does not belong there - a foreign body, hematoma, or thrombus - while excision cuts out a portion of the body part itself.
ResectionResection is the whole-body-part counterpart to excision and applies when the entire anatomical region's involved structure is taken rather than a portion.
DrainageDrainage can also be mistaken for excision when fluid rather than solid tissue is removed; drainage takes out fluids, excision takes out tissue.
